Description

The ABB 3HAC021799-003 is a high-performance brushless AC servo motor engineered for precision motion control within the ABB IRB1600 industrial robot series. This unit functions as the dedicated drive for Axis 4 on standard IRB1600 models and serves both Axis 4 and Axis 5 positions on the IRB1600ID variant. It integrates a factory-configured precision pinion gear assembly, ensuring optimized torque transmission and accurate robotic articulation while simplifying mechanical alignment during replacement.

Features

• Integrated servo motor and precision pinion gear assembly for seamless robotic integration.
• High dynamic response with low rotor inertia (0.015 kg·m²) for rapid acceleration and deceleration.
• IP67-rated housing with sealed connectors to ensure reliable operation in harsh industrial environments.
• Equipped with a 20-bit multi-turn absolute encoder and resolver backup for high-resolution position feedback.
• Compatible with DRIVE-CLiQ interfaces and IRC5 controller systems.
• Integrated thermal protection (PTC/KTY) and STO (Safe Torque Off) readiness.

Applications

• Material Handling: Automated loading and unloading for CNC and injection molding machines.
• High-Speed Assembly: Precise component placement for electronics and automotive production lines.
• Arc Welding: Synchronized multi-axis motion for consistent torch positioning along metal seams.
• Cutting and Deburring: Precision trimming and water-jet cutting of plastic or metal components.
• Packaging and Palletizing: Rapid picking and sorting operations in consumer goods manufacturing.

Technical Specifications

Installation Guidelines

• Safety First: Completely power down the robot controller and engage all mechanical axis brakes or provide external support to the robot arm before beginning work.
• Seal Integrity: Always replace the O-ring (ABB part number 3HAB3772-81) with a new, greased version to ensure an oil-tight seal with the gearbox.
• Pinion Alignment: Align the motor pinion gear carefully with the internal gear teeth. Insert the motor into the cavity until the flange is flush; do not force or hammer the unit to avoid damaging the internal encoder.
• System Configuration: Ensure the controller is running RobotWare 5.0 or later and clear all axis-related faults upon startup.

FAQ

What is the 3HAC021799-003?

The 3HAC021799-003 is a factory-original rotational AC servo motor with an integrated pinion gear, specifically designed for the ABB IRB 1600 and IRB 1600ID robotic arms.

Which robot models is this motor compatible with?

This motor is engineered for the Axis 4 position on the IRB 1600 and the Axis 4-5 position on the IRB 1600ID. It may also be utilized in specific configurations of the IRB 360 and IRB 1520ID.

What should I check if the motor fails to operate after installation?

Verify that all power and feedback cables are securely seated. Ensure the robot controller recognizes the motor during the boot sequence and check for any active axis-related error codes in the controller logs.
